scoray [572]

The given question is incomplete. The complete question is:

A gas has a volume of 590 ml at  a temperature  of 0^0C.What volume will the gas occupy at 30.0^0C. Which gas law is this?

Answer: 655 ml , Charle's Law

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=590ml\\T_1=0^oC=(0+273)K=273K\\V_2=?\\T_2=30.0^0C=(30+273)K=303K

Putting values in above equation, we get:

\frac{590}{273}=\frac{V_2}{303}\\\\V_2=655ml

Thus the volume at 30.0^0C is 655 ml

Answer: 23.53g

Explanation:

5.2/(2x16) = 0.1625 mol

0.1625 x 2 = 0.325 mol

0.325 x (23 x 2 + 16 x 2) = 78 x 0.325 = 23.53g
